Canadian Forces Day is a holiday that celebrates the Canadian Armed Forces, their heritage, and their personnel. It is observed annually on the first Sunday in June. Although it is not a public holiday, it is marked with relevant events and activities across the country.

The Canadian Armed Forces (Forces armées canadiennes), also known as Canadian Forces (les Forces canadiennes), is Canada's unified armed force. It comprises the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force. The Canadian Forces is managed by the Armed Forces Council. The CF in its current form was established in 1968 by the Canadian Forces Reorganization Act. Currently, Canada's military has about 199,000 personnel (both active and reserve).

Canadian Armed Forces Day (Journée des forces armées) was established to honor all members of the country's Armed Forces, including active personnel, reserve personnel, and veterans. It is celebrated with official speeches and addresses, solemn ceremonies, and other events. On this day, Canadian citizens have an opportunity to recognize the contribution of CF members to security and peace, express gratitude and appreciation, admire their valor, bravery, dedication, and commitment.
